Greece shows the flaws in pursuing a common monetary policy response to economic shocks across the EU

To what extent is the Greek debt crisis a function of wider flaws in the design of the single currency? Bruce Morley writes that while Greece’s debt already exceeded 100 per cent of GDP in the 1990s, it is not simply the size of a country’s debt that determines whether it is sustainable. He argues that the real problems illustrated by Greece stem from the application of a common monetary policy across the Eurozone despite key structural differences between individual Eurozone economies.
